Measuring eye pressure after vitrectomy using different devices
Reliability Evaluation of Intraocular Pressure At Day 1 Following Vitreoretinal Surgery, Comparing Goldmann Applanation Tonometry (Gold Standard) to Icare and Accupen
This study is testing two new portable devices for measuring eye pressure after eye surgery to see if they work as well as the traditional method.

What this trial studies
This prospective controlled study aims to evaluate the accuracy of two portable intraocular pressure (IOP) measuring devices, Icare and Accupen, compared to the traditional Goldmann applanation tonometry (GAT) following vitreo-retinal surgery. Participants will have their IOP measured one day post-surgery using all three devices to determine if the newer methods provide reliable measurements. The study seeks to address the need for less cumbersome and portable alternatives to GAT, which has been the gold standard for decades. Previous studies have shown mixed results for these devices, highlighting the necessity for further investigation in a post-operative context.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 18 and older who have undergone vitreoretinal surgery.
Not a fit: Patients with corneal dystrophy, recent corneal surgery, or other significant corneal issues may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a more convenient and reliable method for measuring intraocular pressure in patients after eye surgery.
How similar studies have performed: While previous studies have shown mixed results for the accuracy of Icare and Accupen, this specific evaluation in a post-operative setting is relatively novel.
